Engine weights how much does a typical v6 engine with a cast iron block weigh.

chevy ! v6 but which one not told ????????
lots really for sure cast iron parts, and some ALUM
you can pretend to buy the parts online doing google search
of block and heads, easy and just look , not leaving the keyboard.
see?
one of these 4 engines. the VIN tells the engine code as does RPO list on car. 4.3L for sure.


THERE ARE 4 ENGINES USED THEN, FOR JUST 4.3l
LB4/L35/LF6/LU3


I see no freeze/core plugs in the heads, (6 sides none)
so we land on short block views
the water pump is stand alone, and can leak in 4 places
1front shaft seal
2rear cover
3,4: rear 2 main bock ports leak. SEEN HERE AS P
YES ON SIDES BUT ONLY 2 FRONT TOP IN CLEAR VIEW

take the problem up with the GM technicians and engineers at the factory
not a problem for fixya site

Here is Holden\'s Alloytec V6 in glorious technical detail.



The global V6 engine is the first V6 engine program to address what Thomas G. Stephens, group vice president, GM Powertrain, says is a vital initiative: to develop world-class engines with fully contemporary features - such as dual overhead cams and variable valve timing - but at a competitive cost structure that allows use of the engines in a global mix of vehicles.

it appears that the 2WD drive LT's have the iron block while the 4WD trucks have the aluminum block

Ah yes then. See here p39 on

If you find the engine is a little different to this, it is probably the older 3VZ with a cast iron block. In that case I need to email you a file.

This engine will probably have a cast iron block, painted black. Depending on which country you are in, some year from 1994 on Toyota changed the V6 to a design with an aluminium block, the 1MZ engine. So have a look to see what the engine block is made of.

the 3100 is a 3.1 litre v6 so that is correct it is a cast iron block with aluminum heads used in several gm cars.

That "mud" is actually rust. Back in the early eighties the EPA began mandating more and more MPG. Quickest and easiest way to begin doing that is to cut down on the vehicle weight. Engine block and cylinder head castings were made thinner and the use of nickel (which is heavier than steel or iron) in the alloy they are cast from was cut back. Nickel acts as a rust inhibitor and also helps as a "binding agent",
(without that nickel in there, blocks rust easily, reacting to the acid buildup as antifreeze deteriorates. Blocks and heads are also more prone to cracking as the nickel is very important, helping hold the iron together on a molecular level.
Flush the block really well, have the radiator flushed separately or it will plug up worse. I have seen some engines that were so badly rusted that the welch plugs needed to be removed to let the rust out. Or, replace it altogether.
Best thing you can do is change the antifreeze and do a simple water flush at least every two years.
If you don't you will be right back in the shop doing this same repair again!
OK, class dismissed!
Good luck!!

This is a very common problem with the 2.2 Liter engine. The Cylinder Head Gasket has most likely failed due to expansion and contraction of dissimilar metals. The Cylinder head is Aluminum and the Cylinder Block is Cast Iron. The Cylinder Head expands at a greater rate than the Cylinder Block creating a Scrubbing Action on the Head Gasket. Another problem on this engine is the passenger side rearmost Cylinder Head Bolt is typically overtightened at the factory distorting the Cylinder Head and causing Gasket Failure directly around that bolt. I have had to resurface cylinder heads and replaced gaskets on many of these engines where these symptoms were described.
